Scumble is free and needs no account of its own. The details, and what it needs to render, are under Installation.

What can it do?

Scumble is a desktop image editor built around AI models. Select part of a picture, or draw boxes on an empty canvas, say what should be there, and the answer comes back as a layer of its own, colour-matched to what surrounds it, that you can mask, blend, filter and export like any other. It renders on your own ComfyUI (on your machine or a remote one), on Comfy Cloud, or through the API keys you may already have for FLUX, GPT Image, Nano Banana, Seedream and more: a key alone is enough, no ComfyUI needed. It is free software (GPL-3.0), runs on Windows today, and is young (0.1.x), so expect rough edges and keep backups of your pictures.

Five things it does well

Every result is its own layer

A result lands over your selection as a new layer, faded in at the edge and colour-matched to the picture around it. The Match slider in the layer's row changes that match at any time, and nothing else is baked in either: mask the layer, erase parts, change its blend mode, put filters and text on top. The picture only becomes one when you flatten.
